Famco Damper Repair: The Sherman Oaks Owner’s Guide

Famco damper repair in Sherman Oaks typically runs $280-$520 installed, depending on whether the throat plate, frame, or full assembly needs replacement. We stock Famco-compatible dampers and hardware on our trucks, and most swaps are completed in a single visit. Homeowners usually discover the problem when smoke backs into the living room on the first cool evening, or when they reach up to close the damper and the handle spins freely with nothing catching.

Which Famco Models This Applies To

Famco built two main damper lines you’re likely to find in Sherman Oaks homes: the cast-iron throat dampers common in pre-1990s fireplaces, and the stainless pivot-arm assemblies used in their later zero-clearance and manufactured fireplace packages. The cast-iron units carry a stamped model number on the frame’s left cheek, usually starting with “FD” or “FDC” followed by the throat width in inches. The pivot-arm assemblies have a small aluminum tag riveted to the frame rail, often faded to illegibility after years of heat cycling.

Here’s the compatibility gotcha: Famco’s 8-inch and 10-inch throat plates look identical from below but have different pivot pin spacing, 2.375 inches versus 2.875 inches center-to-center. Measure wrong and the replacement plate won’t seat. We carry both pin configurations, plus the stainless aftermarket equivalent from Gelco that matches Famco’s geometry exactly and typically outlasts the original cast iron in our dry San Fernando Valley climate, where thermal shock from rapid temperature swings is what cracks most throat plates.

We’re an independent service provider, not affiliated with Famco. We source through Haven’s buying network, which includes Famco OEM parts when available and Gelco, HeatShield, and DuraFlex equivalents when they’re the better value.

Signs Your Famco Damper Repair Is Failing

• The handle turns but the plate doesn’t move. The linkage pin has sheared or the worm gear has stripped. This is the most common failure we see in Sherman Oaks, especially in the wood-framed homes along Ventura Boulevard where fireplaces get heavy winter use. The pin is a $12 part; labor to reach it is what drives the repair cost.
• Smoke spills into the room on start-up. The plate is warped or the frame has shifted, leaving a gap even when “closed.” In older Famco cast-iron units, the frame ears can sag from decades of thermal cycling. A camera inspection shows the gap size exactly.
• You feel cold air dropping even when the damper is shut. The plate isn’t seating fully against the frame, or the fiberglass rope seal has burned away. This is the silent efficiency killer, most homeowners don’t notice until their heating bill jumps.
• The plate is visibly cracked or rusted through. Cast iron doesn’t fail gracefully; once cracked, the plate will eventually drop into the firebox. We caught one last month in a 1986 build near Dickens Street that the owner had been ignoring for two seasons.
• The damper won’t open fully. Creosote buildup on the frame rails, or the pivot pin has corroded in place. This is dangerous: a restricted flue causes incomplete combustion and carbon monoxide risk. Don’t force it.

Replacement Cost & What’s Included

What drives the range: accessibility (how much firebrick needs coming out to reach the frame), whether the smoke chamber needs parge coating while we’re in there, and whether you want the OEM Famco part or the Gelco stainless equivalent. Every quote is written before work starts, Clause 1 of the Haven Standard. The camera doesn’t lie, and neither does the written quote. Warranty is 365 days on labor, manufacturer’s warranty on the part itself. You’ll walk away with photos of the installed assembly, the written scope, and the written warranty.

DIY or Call Us?

There’s exactly one safe DIY check: with the fireplace cold and a flashlight, look up the flue and confirm whether the plate moves when you work the handle. If it doesn’t, stop there. The rest of the job involves working inside the firebox throat, often on your back, with your arms above your head, in a space lined with sharp refractory edges. The pivot pins are under spring tension on some Famco models; slip and the plate drops. We’ve also seen homeowners crack the firebrick trying to pry out a seized frame, turning a $400 damper job into a $2,000 firebox rebuild.

We carry Famco-compatible plates, pins, and full assemblies on our trucks. Most Sherman Oaks calls are same-day or next-day. Call (424) 414-6048 and we’ll confirm your model and give you a written price before we dispatch.
